Overview: VPR220, VPR221
Vishay Foil Resistors Bulk Metal® Foil Technology Precision Foil Power Resistors in TO-220 Configuration with TCR of ± 2 ppm/°C, Tolerance of to ± 0.01 % and Power Rating to 8 W Any value at any tolerance within resistance range
Models VPR220 AND VPR221, made from Vishay Bulk Metal® Foil, offer low TCR, high stability, tight tolerance and fast response time in a small, molded resistor. Model VPR220 is a 2 lead device. Model VPR221 is a 4 lead Kelvin connected device. The 4 leaded version is highly remended for precision applications requiring ohmic values of 100R or less.
